Rates of flu-like infection in patients with affective illness.
Studies of immunologic profiles of depressed patients are suggestive of chronic viral infection and several investigators have found specific viral protein in some depressed patients. Moreover, several psychotropic drugs have anti-viral activity and can inhibit viral replication. In this preliminary report, we retrospectively examined the rate of reported flu-like episodes before and during psychotropic drug treatment in 236 affectively ill patients: 177 receiving lithium prophylaxis and 59 receiving chronic antidepressant medication. We observed a small but significant reduction in the mean rate of reported flu-like illness during lithium therapy (P < 0.001), with a greater reduction in men vs. women (P < 0.05). We also found a modest reduction in reported flu-like illness during chronic treatment with antidepressants (P = 0.08). Although these observations are preliminary in nature, they complement earlier reports that some psychotropic drugs may have anti-viral activity.
